摘　　要：采用箱体结构作为现浇空心楼盖结构内模,形成空心双向板,可大大降低楼盖自重,具有混凝土用量少、结构自重轻、地震作用小、隔声隔热效果好等优点,综合效益显著。As box structure is employed as inner form of cast-in-situ concrete slab to form hollow two-way slab, the slab deadweight is greatly reduced. With less concrete quantity, light deadweight and good resistances to earthquake, sound and heat, it has obvious multi-benefits.
